You sample 1,000 individuals from a large population for the mn blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). they are typed accordingly:

Answers

Co-dominance in the mn blood group means that both allele characteristics are expressed in the organism.

What is co-dominance?

Co-dominance is a form of inheritance whereby two or more alleles for a given trait are both dominant such that when they both appear in an organism, the phenotype of that organism reflects the characteristic of both traits.

Co-dominance is usually seen in blood group typing.

In blood group typing, there are two alleles that A and B which are both dominant. When both alleles are present, the blood group is AB and the phenotype of the organism is a result of the properties of both alleles, thus allele A and B are said to be co-dominant.

Therefore, co-dominance in the mn blood group means that both allele characteristic are expressed in the organism.

The cycle only involves the lithosphere, hydrosphere, and biosphere, with no role in the atmosphere. The reason the atmosphere is not involved in that at the natural temperature and pressure of the environment, phosphorus and its compounds are usually in solid or ionic (usually phosphate ion) form.
